Applicability of the CERAD neuropsychological battery to Brazilian elderly
Bertolucci PH, Okamoto IH, Brucki SM, Siviero MO, Toniolo Neto J, Ramos LR.. Arquivos de neuro-psiquiatria, 2001-09-01
Topic: Risk, prevention and care in population studies
There is a limited choice of psychometric tests for Portuguese speaking people which have been evaluated in well defined groups. A Portuguese version of CERAD neuropsychological battery was applied to a control group of healthy elderly (CG) (mean age 75.1 years/ education 7.9 years), 31 Alzheimer disease (AD) patients classified by clinical dementia rating (CDR) as CDR1 (71.4/ 9.0) and 12 AD patients CDR 2 (74.1/ 9.3). Cut-off points were: verbal fluency-11; modified Boston naming-12; Mini-mental State Examination (MMSE) -26; word list memory-13; constructional praxis-9; word recall-3, word recognition-7; praxis recall-4.
Key findings
- A Portuguese version of CERAD neuropsychological battery was applied to a control group of healthy elderly (CG) (mean age 75.1 years/ education 7.9 years), 31 Alzheimer disease (AD) patients classified by clinical dementia rating (CDR) as CDR1 (71.4/ 9.0) and 12 AD patients CDR 2 (74.1/ 9.3).
- Cut-off points were: verbal fluency-11; modified Boston naming-12; Mini-mental State Examination (MMSE) -26; word list memory-13; constructional praxis-9; word recall-3, word recognition-7; praxis recall-4.
- There was a significant difference between CG and AD-CDR1 (p<0.0001) for all tests.
- There was a less significant difference for constructional praxis and no difference for Boston naming.
Why it matters
This study applied a Portuguese version of the CERAD neuropsychological battery to healthy elderly people and Alzheimer's disease patients in Brazil and reported cut-off scores. It is a test-validation study and does not test any treatment, cure, or prevention.
Study details

How this study scored 35/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 34 of the 96 points we could judge it on, which is 35 out of 100.
